Getting to know all the components of a vessel might be a complicated task. However, Sailingyes is here to help you out through this introduction on the sailing ship shroud and rigging – two of the most important mechanisms of a watercraft.
Technical Definition
A shroud is a set of cables or ropes that keep the ship’s mast in its place. The main purpose of this structure is to create pressure lines on each side of the boat mast, holding the pole(s) tight.
Such a cable usually connects the mast/pole to the gunwale, but some models utilize channels to transfer the linking points. A channel, therefore, is an additional structure attached near the gunwales to create a panel for shroud joins.
Shroud and Rigging Compared
To understand the concept of shrouds (aka sidestays) you must get to know the ship rigging. Vessels use systems of lines, ropes, and/or links to stabilize masts and sails. These systems are called rigging and sidestays are a member of them, being an arrangement of ropes to balance out the sheet holding pole(s).
So, rigging is a general term referring to all the cable structures balancing out specific components on the deck. That’s while the term shroud points out a particular member of the rigging system, specialized in cleaving to the masts/poles.
Shroud vs. Forestay and Backstay
A forestay is a cable that connects the jib or mast to the bowsprit, whereas the backstay links them to the backend of the vessel—mainly to the transom. However, a sidestay does the same thing in the right and left flanks of the boat.
The goal of a forestay is to stop the mast from falling backward. And a backstay generates an opposite pressure line to do the same thing on the contrary direction. So, their function is comparable to the shrouds as the only two major differences here is the direction in which they hold onto the mast and adjustability. (See below).
Some crafts own a running forestay and backstay, which allows the skipper to adjust them when necessary. Some other boats/ships also combine the running systems with the standing ones to offer stability and versatility at the same time. A sidestay, however, is always standing (or fixed) and the mariners do not utilize them as an adjustment tool.
Terminology and Jargon
- Deadeye is a spherical shape at the end of each sidestay rope that allows the lanyard to pass through its holes and create more tension. (It’s called so because its 3-hole models look like skulls).
- Lanyard is a line that runs back and forth between the deadeyes’ holes.
- The mainsheet is the rope that allows controlling the mainsail of a boat.
- The bowsprit is a horizontal pole-like structure attached to the bow. It allows the forestay to extend even further, creating more adjustability.
- Running rigging is a scheme of ropes/lines that the skipper uses to regulate the sheet(s) and stay(s).
- Standing rigging refers to a group of links/ropes that hold the upstanding components in their place.
- The mast is a flagpole-like structure carrying the sail(s).
Modern Sailing Ship Shrouds vs. the Classic Types
The main difference between the modern and traditional versions of ships’ shroud is the material. Older vessels used to utilize steel as the main material to create the rigging lines and deadeyes. Modern ones, however, prefer employing innovative fabrics such as stainless steel wire, stainless steel rod or synthetic fiber.
The earlier fabrics where strong enough to bear incoming pressures, but they were not easy to maintain or inspect. Some cracks could stay invisible to the naked eye on the old versions of shroud ropes.
Modern products are easier to maintain and their materials make it uncomplicated to check for cracks or weaknesses. Of course, not all novel fabrics are such. Solid rod stainless steel, for instance, offers better aerodynamic usage but it requires x-raying when it comes down to safety and/or crack checks.
Categorizing Vessels by Their Rigging System
-
Sloop:
Being the most common type, a sloop rig is a cost-effective option, carrying the largest sails. It contains 1 sail and 1 headsail while having the least complicated running and standing rigging structure. Since it doesn’t contain many forestays, backstays, and shrouds, the number of winches and controlling lines are limited, agreeing much simpler navigation.
Moreover, there are no extra sheets to cover the main; so, you can experience the best windward movement with this rig type. However, since having only one mast makes it hard to generate enough force, sloops employ very large sheets. This makes it difficult to change the boom position in vessels which have hank.
-
Cutter:
It has 1 mast, but there are 2 sails fixed to it. The larger sail in front is called a jib, whereas the smaller one is entitled a staysail. Because of this spectacular rig system, you will have more sidestays and running rigging lines to deal with. But it offers more navigating options as you can reef the sheets or utilize only one of them (usually the staysail) to navigate on the extremely windy weather conditions.
A downside to a cutter rig is that you cannot depend on its tacking performance. That’s because the stay sheet may get in the way of the jib and make it thorny for amateur mariners to tack.
-
Ketch:
Offering a flexible sail plan, a ketch has 2 masts and 1 headsail. one of the masts is right in front of the rudder and it’s called the mizzen mast. The mainmast, however, contains the headsail and the mainsail, and it’s usually taller than the mizzen mast.
Due to having 3 sheets, the number of shrouds, stays, and lines that you must deal with is more than other rig types. But the upside of owning such a system is being able to navigate with more options. That said, you can either reef the headsail and the main to continue with the mizzen mast sheet or utilize all of them at once.
-
Yawl:
This rig has 2 masts and 1 headsail while containing a short mizzen mast behind the rudder post. Utilizing this boat would let the skipper navigate with more navigating options, but the downside is that the mainsail covers the mizzen mast during the upwind movement. This can reduce the efficiency of having an extra mast, leaving you with only more components (e.g. ropes, sidestays, winches, etc.) to handle.
Safety Checking the Lines and Deadeyes
A small failure on the deck may effortlessly lead to drastic problems in the future. A minor crack on a sidestay or deadeye, for instance, may leave you with a broken rig and an unstable mast. So, a 20- to 30-minute rigging inspection is vital before heading out on the water. Here’s how to do so.
Things You Need
- A magnifier
- A Scotch-Brite pad
- Some lubricant
How-to Instructions
- First, walk around the deck and visually check the fittings. See if there’s any sign of rust or corrosion in the area.
- Next, get down on your knees to inspect the shrouds and the chainplates. Clean the fittings up and utilize your magnifier to see if there’re any cracks.
- Look for any sign of pulling or lifting in the chainplates while inspecting the cracks around the sealant—if it goes through the deck.
- Give a hand-feel for the tension of the stays. Try to determine whether or not they all feel about the same and none of them is looser than the rest.
- Do the same thing for the forestay and backstay, making sure they are properly fixed. If your forestay is fitted with a roller furling mechanism, you better check it over carefully as well. (Forestays are more likely to get damaged during docking).
